OPERATION WARNING: Do not allow familiarity with products to make you careless. Remember that a careless fraction of a second is sufficient to inflict serious injury. WARNING: Always wear eye protection with side shields marked to comply with ANSI Z87.1. Failure to do so could result in objects being thrown into your eyes resulting in possible serious injury. APPLICATIONS You may use this product for the purposes listed below: Sanding wood or wood product surfaces Sanding steel surfaces Removing rust from steel surfaces SANDPAPER SELECTION Selecting the correct size grit and type sandpaper is an extremely important step in achieving a high quality sanded finish. Aluminum oxide, silicon carbide, and other synthetic abrasives are best for power sanding. Natural abrasives, such as flint and garnet, are too soft for economical use in power sanding. In general, coarse grit will remove the most material and finer grit will produce the best finish in all sanding operations. The condition of the surface to be sanded will determine which grit will do the job. If the surface is rough, start with a coarse grit and sand until the surface is uniform. Medium grit may then be used to remove scratches left by the coarser grit and finer grit used for finishing of the surface. Always continue sanding with each grit until surface is uniform. NOTE: DO NOT use sander without sandpaper. Doing so will damage the sanding pad. INSTALLING STANDARD SANDPAPER See Figure 2, page 13. Inspect sandpaper before installing. DO NOT use if torn, cracked, or defective. Unplug the sander. If replacing sandpaper, remove old sandpaper. To remove paper, release the rear paper clamp by holding the tab and lifting up on the lever, disengaging the lever from the base, and allowing the lever to lower. Pull the front paper clamp open and remove the sandpaper. Holding the front paper clamp open, insert end of new 1/4 sheet sandpaper approximately 1/4 in. under the paper clamp. Release the paper clamp to secure the sandpaper. Insert end of new 1/4 sheet sandpaper approximately 1/4 in. under the rear paper clamp. Making sure to hold the sandpaper tight against the sanding pad, lift up on the tab to pull the lever back into place. Apply downward pressure to conform sandpaper to platen. Multiple sheets of sandpaper can be installed at one time for convenience. PAPER PUNCH See Figure 3, page 13. A paper punch template is supplied with the sander for aligning and punching holes in sandpaper. The punched holes must align with the holes in the sanding pad. An outline of the sander is printed onto the paper punch to help you correctly position the sandpaper before punching. Install sandpaper on the sander. Align sanding pad over the paper punch. Push down on sander. INSTALLING PRESSURE SENSITIVE ADHESIVE (PSA) SANDPAPER See Figure 4, page 13. Inspect sandpaper before installing. DO NOT use broken or defective sandpaper. Unplug the sander. If replacing sandpaper, remove old sandpaper by peeling it off the sanding pad. If removing standard sandpaper, see Installing Non-Adhesive Sandpaper. Carefully peel adhesive backing from new 1/4 sheet sandpaper. Position sandpaper, making sure front edge of sandpaper is aligned with front edge of the sanding pad, then carefully press sticky side of sandpaper on pad. Note: Sandpaper must be aligned with the front edge of the pad for proper functioning of the flush sanding feature. REMOVING PSA SANDPAPER BEFORE STORAGE Do not store the sander with the sandpaper installed. Heat generated from sanding causes the pressure sensitive adhesive to flow and form a tight bond between the backing pad and sandpaper. Removing the sandpaper soon after you have finished a sanding operation avoids letting the adhesive set up. If the sandpaper is left on the backing pad for an extended period of time after use, the adhesive will set up and cause the sandpaper to become difficult to remove. PSA sandpaper may also tear when removing. When this situation occurs, it becomes difficult to clean the backing pad for the next sheet of sandpaper. 8 - English
